PUMP-Ron CONNECTION;

SPECIFICATION forming part of Letters Patent No. 547,906, dated October 15, 1895.

Application mea .tpm 24,1895.

To all whom itmay concern:

Beit known that we, EILLMORI; M. WEL- sHIMER and PHILIP H. WELsHIMnR, citizens of the United States, residing at Columbia City, in the county of Whitley and State of Indiana, have invented a new and useful Pump- Rod Connection, of which the following is a specification.'

The invention relates to improvements in pump-rod connections.

The object of the presentinvention is to improve the construction of connections or couplings for attaching pistons of windmills to pump-rods and to dispense with the ordinary rigid pin or fastening device often employed for positively interlocking such parts and to provide a coupling or connection which will be simpleand inexpensive and which may be readily adjusted for permitting the pump-rod to move freely on the pitman or the adjacent part when it is desired to uncouple the pumping and entirely separating the pitman and Another object of the invention is vto enable the .pitman and the pump-rod of a windmill to be readily connected or coupled when desired without adjusting, fitting, andiuter- The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim heretoappended.

In the drawings, Figure 1 is a longitudinal sectional view of a couplingor connection constructed in` accordance with this invention and shown applied to a portion of a pitman and the upper end of a pump-rod.- Fig. 2 is a perspective view of the coupling or connection. Fig. 3 is atransverse sectional view of the saine.

Like numerals of reference indicate corresponding parts in all the figures of the draw- 1ngs.

` 1 designatesa bar, consistin g, preferably, of a casting vand provided with side anges 2 and having a rectangular socket 3 at its lower end. Its upper end is secured to a windmillpitman 4, and it is provided on its interior' with a longitudinal strengthening-rib anda sel-In Instante. montati.)

portion of the bar 1 and extends longitudinally thereof between the side iianges 2 and. terminates at the lower end of the bar. Its

upper end is riveted or otherwise secured to` the bar adjacent to the lower terminus of the longitudinal rib, and the lower portion of the resilient plate frictionally engages the upper' end of a pump-rod 7, which tits in the socket 3 of the bar 1. The bar is provided adjacent to its lower terminal with an enlargement or boss 8 and has a threaded perforation receiving a screw 9, which-is provided at its outer end with a hand-wheel 10, and which has its inner terminal engaging the resilient plate and adapted to force the same into frictional Contact with the pump-rod.. B'yyturn'ing the wheel to the right or to the left the pump-rod may be coupled or uncoupled, and this manner ot' engaging the pump-rod obviatesv the positive interlocking o f the parts, and the pump-rodwhen uncoupled is adapted to slide freely in the socket of the bar 1, or the latter is adapted to reciprocate on theupper portion of the pump-rod, and it is not necessary to disconnect the parts entirely to effect lthe op'- eration of uucoupling.

It will be seen that the coupling or connection is exceedingly simple and inexpensive i'n construction, lthat itis strong and durable and uncoupled from the pump-rod without entirely disconnecting and separating the parts.

Changes in the form, proportion, and theminor details of construction may be resorted A resilient plate 6 is arranged on the lower l to without departing from the principle or sacrilcing any of the advantages of this iuvention.

What we claim is-f- A wind mill pitman and pump rod connection, comprising a barhaving lside Hanges, and provided at its lower end with a socket and having intermediate of its ends the transverse and-longitudinal supporting ribs, the transverse rib being arranged to form a stop or support for a pitman, a longitudinal resili- ICO ent plate arranged between the finnges of the bar and having its upper end located adjacent to the lower terminal of the longitudinal rib and secured to the barthe lower portion of the resilient plate being free and arranged in the socket, and a screw mounted on the bar and engaging the resilient plate and provided at its outer end with a hand wheel, substantially as described.
